AB - Very little property data on this common turbine blade alloy has been published. As longer hours of service are accumulated, maintenance considerations such as developing optimum component life strategies and repair processes become important. The lack of specific material data hampers the effort of users and repair facilities to achieve optimum service from this alloy.This study measured some of the basic mechanical and metallurgical characteristics of this poly-crystalline nickel base superalloy. Tensile and short term creep rupture properties as well as microstructural and fracture characteristics are presented. Both the as-heat-treated and thermally exposed characteristics at two different temperatures are examined.
